Hey! I love your addon. It's so clean and Classic-like. Good job!

And I have a request:

I'd like to see an additional choice from the dropdown called "Magic Resistance" (or "Spell Resistance"?). Conveniently enough, there are five types of magic that a character can have resistance for, which suits the five lines in your stat UI.
I would also like to see the CharacterResistanceFrame hidden (possibly with an option checkmark in the settings UI).

Keep up the good work. Thanks!
